INSTALLATION
The kit supplied is designed for vertical or horizontal mounting on a solid wall. For mounting on other walls, you need suitable fasteners (not included in the scope of delivery). Make sure that the wall is suitable for mounting. We strongly recommend having the panel installed by a qualified electrician or an authorised specialist company. The heater must be at least 20 cm away from all objects, walls, etc. The distance to the floor must be at least 20 cm.
Note: Before installation, you should attach the guard to the heater for safety reasons.

OPERATION
General introduction to the control system
The series has built-in WLAN control, which means that no additional thermostat is required to control the heater. As soon as the heater is connected to the app, the smartphone will take over control and communicate with the control unit. If the internet is not working at home, it is still possible to operate the heating manually via the control panel or the remote control. As soon as the heater is connected to the WLAN again, the smartphone takes over the control again.
